TECHNICAL FIELD

The present invention relates to the field of inflatable model deflation, and more particularly to an anti-collapse structure for an inflation tube of an inflatable model, and a blower comprising same.

BACKGROUND ART

Because the inflatable model has the advantages of light weight, convenient carrying and easy application, it is widely used in large-scale advertising, inflatable amusement facilities and other fields. After the inflatable model is used, the internal air needs to be emptied to be removed and transported. Since the inflatable model usually has only one air hole, the process of deflation for a large inflatable model is very slow, and an operator will spend a lot of time waiting for the air in the inflatable model to be exhausted. However, if a suction fan is specially provided to pump out air for the inflatable model, the cost is too high, and the frequency of use is low, resulting in waste.

An air inlet device is arranged on a blower such that the blower is added with the deflation function for the inflatable model on the basis of the original inflation for the inflatable model. In the procedure in which the device carries out the deflation operation for the inflatable model, the inflatable model gradually falls due to its own weight during pumping out the internal air. When the air in the inflatable model is almost completely pumped out, the falling of the inflatable model tends to lead to the falling of the nozzle inside an airflow channel or itself, causing the airflow during deflation to be reduced or even the airflow channel to be completely blocked, so that the deflation operation cannot continue when there is still a large amount of air in the inflatable model, which affects the deflation effect and efficiency.
